Abstract

FIELD: electrical engineering. SUBSTANCE: nonsinusoidal voltages applied to battery and battery current are recorded and expanded into harmonic F-series, and by values of amplitudes and initial phases of voltage and current harmonics, complex impedance of battery for each harmonic are determined and also their resistive and reactive components. By frequency characteristics of chemical supply source one can judge serviceability of supply sources, their condition, state of charge and carry out automatic control of charging process. EFFECT: increased accuracy of checking of amplitude-frequency and phase-frequency characteristics of all types of storage batteries within wide frequency.

To do this, the non-sinusoidal voltage and current applied to the battery are recorded and, expanding them into the Fourier harmonic series, the complex resistance of the battery for each harmonic, their active and reactive components are determined from the amplitudes and initial phases of the voltage and current harmonics. Knowledge of the frequency characteristics of HIT allows us to judge the operability of current sources, technical condition, degree of charge, and to synthesize systems for automatic control of the charge process.
